Description

[Detailed explanation of the idea] The present invention relates to an accordion type door lock.

The purpose of the present invention is to construct the entire sickle part, the lock cylinder lock part and the sickle operation bundle part separately,
These can be immediately integrated when attached to an accordion-type gate.

An embodiment of the present invention will be described below with reference to the drawings.
1 is an inner mounting frame, 2 is an outer mounting frame, and 3 is a sickle support case.

The inner and outer mounting frames 1 and 2 are provided with connection legs 1at2a and bundle mounting holes 1 in order from the top to the bottom.
b, 2b, cylinder lock body parts 1c, 2c, connection leg 1a*
2a is provided.

In the inner mounting frame 1 and the outer mounting frame 2, which face each other, a connecting rod 4 is provided between the upper and lower connecting legs 1at2a.

Although not shown, one end of the connecting rod 4 is provided with a threaded portion, and the other end is provided with a female threaded portion. It is screwed onto the inner mounting frame 1 when installing to the gate.
A connecting screw 5 is inserted into a hole passing through the connecting leg 1a of the connecting rod 4, and is screwed into the female screw portion of the connecting rod 4, thereby fixing the connecting rod 4.

In the bundle attachment holes 1b and 2b, a sickle operation bundle 6.6, which also serves as a door operation, has its shaft portion 6a.

6a so as to be rotatable.

A square hole 6b is formed in both shaft parts 6a, and a square operation shaft 7 is inserted into the square hole 6b, so that the operation shaft 7 is provided between the sickle operation bundles 6 and 6. Although not shown, the operating shaft 7 and the shaft portion 6a of the sickle operating bundle 6
A mounting screw is provided between them.

The cylinder lock body parts 1c, 2c are provided with a shutter-equipped rotor part 8.8 having a built-in plate tumbler as is known in the art.

Floating connectors 9, 9 are attached to the rotor parts 8, 8, respectively, and a square locking shaft 10 is provided between the floating connectors 9, 9 through their square holes 9a.

Inside the sickle support case 3, a sickle 12 is rotatably supported by a shaft 13, and the sickle 12 is urged by a spring 14 so as to always protrude from the front opening 3a.

A sickle drive plate 15 is provided on the shaft 13, and the sickle drive plate 1
A protrusion 15a provided on the sickle 5 engages with a circumferential recess 12a provided on the pivot shaft of the sickle, and the sickle drive plate 15 and the sickle 12 are assembled with a free movement interval between them.

Reference numeral 16 denotes an operating cam that is rotatably provided with respect to the sickle support case 3, has an insertion hole 16a for the operating shaft 7, is engaged with the receiving portion 15b of the sickle drive plate 15, and is connected to the sickle supporting case 3. When the operation shaft 7 is rotated by the operation bundle 6, the sickle drive plate 1
5 to the sickle 12 in the clockwise direction to retreat the sickle 12 from its latched or locked position into the sickle support case 3.

A lock cam 17 is rotatably provided to the sickle support case 3, and has an insertion hole 17a for the lock shaft 10.

An unlocking notch 17b is formed on the outer periphery of the lock cam 17. In the unlocking state shown in FIG. When the cylinder lock S is operated, the lock cam 17 moves to the position shown in FIG. 2, and in this state, the protrusion 15a abuts against the lock cam 17, so the sickle 12 is in a locked state.

Note that 18 is a leaf spring for positioning the lock cam 17.

A tapered abutment part 12b is formed at the tip of the sickle 12 for the opposing seat, and the sickle, which is always in a protruding state when the accordion-type gate p is closed, abuts against the seat and moves upward. While rotating, they automatically engage.

In addition, 19 is a front decorative board, and 20 is a lid plate.

As described above, the present invention separately configures an inner mounting frame and an outer mounting frame each provided with a sickle support case portion and a cylinder lock or sickle operation bundle, and connects the connecting rod, operating shaft, and lock shaft. Since the sickle metal or its operating part can be easily installed at the end of a relatively wide gate, the sickle metal or its operating part can be easily installed at the end of a relatively wide gate.
